It's all about eyelove, my friends. Finally tonight, the outgoing freshman at the U.S. Naval academy are officially plebes no more. Damn the torpedoes. Full speed ahead! Reporter: It's a time-honored tradition at the naval academy. Freshman plebes trying to scale the monument to remove a plebe known as a Dixie cup and replace it with the hat of a mid-shipman. It represents the class transition from plebes to mid-shipmen and symbolically ends their first year at academy. The catch, the 23-foot obelisk is greased with lard. Upper classmen are standing by with hoses. The pyramid bringing to mind the zombies in "World War Z." This year's attempt was live-streamed. Thousands tuning in to the riveting spectacle of teamwork, tum sxblz ultimately triumph. The fastest recorded time was the class of 1972 who clocked in at 1:30. But back then the monument was not greased. The slowest was the class of 1998, who took just over four hours to complete. As for the class of 2020 -- Punsh, push. The challenge lasted two hours 21 minutes and 21 seconds. A valiant effort for these unrelenting underclassmen. Good for them. As they say in the Navy, not for self but country. Thank you for watching ABC news. Tune in to "Gma" tomorrow for much more on the events in Manchester. And as always, we're online at abcnews.com and the "Nightline" Facebook page. Thanks for the company, America. Good night.
